COMPARISON OF LIKERT SCALE WITH SEMANTIC DIFFERENTIAL

Both types of scales can assess attitudes, but have different formats.

Likert (summated rating) scale

Fixed response choices (e.g., agreement or frequency)

Items concern different aspects or descriptions of target

Semantic differential

Fixed target for attitude evaluation

Items are bipolar adjectives that concern target
